Summary: In this study, the speed of the interfacial polymerization reaction was controlled by controlling the diffusion rate of the aqueous monomer, thereby affecting the thickness and surface morphology of the polyamide layer. Polyethylene oxide (PEO) was added to increase the viscosity of the aqueous phase and slow down the reaction rate. Choline chloride (CC) was then grafted onto the surface of the polyamide membrane for secondary modification. The addition of 1% PEO resulted in the best performance of the composite membrane, and after CC modification, the rejection rate of (NaSO4)-S-2 was more than 96% with a permeation flux of 125.9 L/(m(2)center dot h center dot MPa). This composite membrane has potential applications in seawater desalination and sewage purification.

Summary: Environmentally friendly polymer membranes for dye contamination removal were prepared from edible calcium alginate. The addition of oligoethylene glycol (OEG) or polyethylene glycol (PEG) to the casting polymer solution and subsequent removal of the OEG or PEG from the membranes through a washing process improved water permeability and tailored the mass transfer channels, resulting in membranes suitable for various membrane separation processes. These modified membranes exhibited increased water permeability and maintained molecular separation performance, making them suitable for applications in nanofiltration and ultrafiltration processes for wastewater treatment.

Summary: Biodegradable metals, such as zinc-based materials, have become popular for biomedical applications due to their ability to assist in tissue healing. This study investigated the combined effect of minor iron addition and a polyethylene glycol (PEG) coating on the surface morphology, degradation, cytotoxicity, and mechanical properties of zinc-based materials. The results showed that the addition of iron and polymer coating had a positive effect on degradation rate and mechanical properties, but led to a reduction in biocompatibility.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
